Hi @astrava,
When embedding the player on a page served over HTTPs, you’ll want to set the delivery_profile.url to a HTTPs endpoint as well, otherwise, the browser will block the connection on “mixed content” grounds.
However, while I don’t know the details for your exact setup, https://video.domain.ca is likely wrong as typically that would reach the Apache on the nodes whereas delivery_profile.url should point to your Nginx, where the VOD module ls loaded.
